I have a 6-burner Wolf 36" gas grill with rotisserie.
I can't recall when I last did a chicken on it. Its been so long ago but I recall it being a real PIA to get the spit centered and bird balanced. Instead, I do bear can chickens if using the gasser (outer 4 burners on, middle 2 off, bird in center).
I love the rotisserie though! I have done pork roasts, pork loins, beef roasts, hams, turkey breasts, and potatoes & wings (with a Napolean tumble basket).
I use the infra red burner in the back and use the outer 4 burners leaving the middle 2 off.
Pork loins - by themselves, bacon wrapped, butterflied and stuffed, bacon wrapped butterflied and stuffed, list goes on. Buy the large ones at Costco that are 30-36" long, cut in 3rds, and now you have 3 meat projects for later.
The tumble basket does excellent for veggies and wings. Its a kind of a PIA to clean though. I stuff the basket halves with frozen Costco wings, quickly snap the basket halves together, then onto the rotating spit and season as the basket spins. I think I can get near 40 wings in the basket for our family of 4.
I had to replace the original motor and spit on my Wolf. I bought this motor

I modified a spit rod to work with it. The motor is stout and the company's warranty is excellent. My switch started getting sporadic after 6-9 months of hard use and they shipped me a new unit with return shipping for unit.
I saw go for it as it lets you try new things!
